breacharbiter: sweep incoming + outgoing htlcs
This commit also adds a BreachConfig to abstract
  the instantiation of the breach arbiter, as well
  as various formatting improvements.

lnd_test: adds breach test for remote hodl
This commit alters the existing retribution
  post breach conf test case with the intention
  of testing the correct response in event that
  the remote party broadcasts a prior state
  while HTLCs have been extended. This serves
  as a preliminary integration for an expansion
  of the breach arbiter integration tests.

  The primary change involves using the new
  htlchodl mode for debugging, which causes the
  remote peer to ignore any intent to settle
  incoming HTLCs. The result is that any
  payments sent to the remote party are held in
  limbo, allowing us to test for these
  conditions more accurately.

  Currently the test case only tests that the
  justice transaction is mined. After we have
  fully integrated the breach arbiter to sweep
  2nd layer HTLCs, this test will be altered
  to check for spends from the appropriate
  inputs.

d65f17f1b1 fuzzing: fixed calculation of serializedSize() in features.go
This commit fixes an incorrectly calculated size of a
*FeatureVector in the serializedSize() function. go-fuzz
found that when calling NewFeatureVectorFromReader, if
a flag is invalid, it is not added to f.flags. However,
it will skip the index that wasn't included. This
becomes a problem when serializedSize() calculates the
length of f.flags via len() which can lead to an index
out of range since certain flags may be missing.

7662ea5d4d invoice: Add invoice package
The invoice package can be used to encoded and decode invoices
in the format defined in BOLT-0011. This format utilizes bech32
encoding to create invoices that can be shared and understood
by the different Lightning implementations.

74322a99be config+htlclink+peer: htlc hodl mode!
This commit adds a new debug mode for lnd
  called hodlhtlc. This mode instructs a node
  to refrain from settling incoming HTLCs for
  which it is the exit node. We plan to use
  this in testing to more precisely control
  the states a node can take during
  execution.

d0685730bd docker: don't specify datadir in lnd container
In this commit, we fix a lingering issue in the execution 
of the lnd container, after the new macaroon based 
authentication was added. With the new authentication 
feature, if the datadir was changed, but `lncli` wasn't 
updated to point to the macaroon path, then none of 
the commands would work. 

To fix this, we simply omit setting the data directory.

90d13cf70c README: fix incorrect links to dev sites
This commit fixes two incorrect links in the readme to
dev.lightning.community and api.lightning.community. The two links were
lacking the http:// prefix, and Github's parser didn't automatically
recognize the new TLD. As a result, the links wouldn't automatically
show as clickable. With this commit, we've added the prefix, ensuring
that the links are properly clickable.

lnwire: properly encode/decode addrs in NodeAnnouncement msg
This commit fixes an existing deviation in the way we encode+decode the
addresses within the NodeAnnouncement message with that of the
specification. Prior to this commit, we would encode the _number_ of
addresses, rather than the number of bytes it takes to encode all the
addresses.

In this commit, we fix this mistake by properly writing out the total
number of bytes, modifying our parsing to take account of this new
encoding.

lnwire: fix bug in wire.OutPoint -> lnwire.ChannelID conversion
This commit fixes an existing, unnoticed bug within the lnwire.
NewChanIDFromOutPoint function. Two lingering issues cause the function
to not do anything at all, meaning that the channel ID, would be the
exact same as the actual txid passed in.

The first issue was that the xorTxid function wasn’t actually XOR’ing
the last two bytes. This was due to the fact that the function wasn’t
taking a pointer to the target ChannelID, meaning that the mutation
wouldn’t be seen outside of the scope of the function. Second, we had
our slicing reversed, rather than buf[30:], we were using buf[:30],
meaning that we were weren’t properly filling the buffer with the lower
2-bytes of the passed index.

lnwire: make test clause within TestChannelIDOutPointConversion stricter
This commit modifies the main test loop within
TestChannelIDOutPointConversion stricter. With this commit, we now

the first in a series of commits to fix a recently discovered bug
within the outpoint to channel ID conversion routines.

funding: properly display pending chan ID within logs
This commit corrects a minor formatting error when logging the pending
channel ID within the logs. Previously, the logging directives and
parameter could cause the pending chan ID to display in a double-hex
encoded format. We fix this by ensuring that we properly slice the chan
ID before printing it, and also ensure that we use the %x formatting
(which will hex encode the bytes) everywhere.

Fixes #331.

d97575d6d2 lnwire: ensure that addrs in ClosedSigned are below 35 bytes
This is a very simple bug that go-fuzz found. If length of an address
within CloseSigned is greater than 34, a runtime error: slice bounds out
of range happens. An error should be returned instead.

lnwire: swap order of MinAcceptDepth and HtlcMinimum
In this commit we reverse the ordering of the MinAcceptDepth and
HltcMinimum fields within the AcceptChannel message. Previously, the
order of these two fields were reversed, meaning the remote peer
would’ve attempted to parse the MinAcceptDepth (as we intended), as
part of the HtlcMinimum, leading to a garbage value.

htlcswitch: properly verify OutgoingCTLV+Timeout when final hop in link
This commit fixes an existing bug in the way we perform validation of
the timelock information as the final hop in the route. Previously, we
would assert that the outgoing time lock in the per-hop payload would
exactly match our time lock delta.

Instead, we should be asserting two things:
   1. That the time lock in the payload is >= the expected time lock
   2. That timeout on the HTLC is exactly equal to the payload

routing: hop-payload for last hop should be the absolute timeout, not delta
This commit fixes an oversight in the path finding code when converting
a path into a route. Currently, for the last hop, we’d emplace the
expiry delta of the last hop within the per-hop payload. This was left
over from a prior version of the specification.

To fix this, we’ll now emplace the _absolute_ final HTLC expiry with
the payload, such that, the final hop that verify that the HTLC has not
been tampered with in flight.

funding: properly verify and apply channel constraints during funding flow
This commit implements some missing functionality as we’ll now properly
validate and generate the various channel flow control constraints
during initial channel funding.

With this commit, we take an additional step towards full spec
compliance as we’ll now properly send over the required channel
reservation, max HTLC’s, and other parameters during the funding flow.

When processing the desired parameters by the remote party, if we think
they’re unreasonable, then we’ll send an Error message and end the
funding flow.

lnwire: fix ordering of the UpdateAddHTLC message on the wire
This commit fixes a diversion from the way the UpdateAddHTLC message is
defined within the specification. We had the HTLC expiry value in the

messages as sent by the other LN implementations.
